Abstract

Unité de lampes flash présentant un support en forme de plaque pour un circuit électrique comportant des lampes flash à combustion. Du côté du support situé à l'opposé des lampes, l'unité présente une plaque non transparente comportant, tout comme le support, face au moins à une lampe flash, un trou à la hauteur duquel est disposée, entre le support et la plaque, une feuille, qui disparaît par suite de l'allumage de la lampe. Le trou ménagé dans le support s'évase depuis le côté des lampes vers le côté opposé et, du côté des lampes, il est plus étroit que le trou ménagé dans la plaque, la partie du support située à l'opposé du trou de la plaque étant munie d'une couleur, qui contraste avec celle de la feuille. Application : unité de lampes flash pour la photographie.
